FLOW  METERS  FOR  STEAM,  AIR 
OR  WATER 

TYPES  F,  FS-4,  FA-4  AND  FW-4 

Introductory 

Carefully  read  this  entire  book  before  installing  the  nozzle  plug 
and  piping,  or  starting  the  meter. 

Some  of  the  principal  operations  are  illustrated  by  small  marginal 
cuts  and  each  view  is  marked  with  the  paragraph  number  to  which  it 
refers. 

The  rules  are  arranged  in  the  working  sequence  suggested  for  the 
operations  that  are  necessary  to  install  the  meter  and  adjust  it  to 
service. 

The  meter  connected  to  nozzle  plug  and  calibrated  for  steam  flow 
is  referred  to  in  these  instructions.  Reference  notes  regarding  other 
meters  and  apparatus  are  introduced  where  necessary. 

Additional  instructions  for  installing  meters  for  air  or  water  flow 
will  be  found  in  their  proper  sections. 

Definitions 

The  Type  F flow  meter  may  be  used  for  measuring  for  either 
steam,  air  or  water.  The  meter  does  not  have  an  indicating  scale. 

The  Types  FS-4,  FA-4  and  FW-4  are  steam,  air  and  water  meters 
with  recording  chart  and  indicating  scale  calibrated  as  desired.  This 
meter  can  not  be  used  interchangeably  on  steam,  water  and  air.

1.  INSTALLATION  OF  THE 
NOZZLE  PLUG 

Example  Installation 


Fig.  1 shows  a front  view  of  the 
Type  FS-4  meter  connected  to  nozzle 
plug  in  a vertical  pipe. 

A close  view  of  the  nozzle  plug  is 
shown  in  Fig.  2.  A part  of  the  pipe 
is  cut  away  to  show  the  tube  of  the 
nozzle  plug  extending  across  the 
inside  diameter. 


Location  of  Nozzle  Plug 

(1)  In  selecting  a location  for 
nozzle  plug  in  any  line  of  pipe,  allow 
space  for  the  piping,  valves  and 
reservoirs  at  the  plug. 

Note. — -For  dimensions  see  Fig. 
29.' 

: (2)  The  nozzle  plug  should  be 
inserted  in  either  a vertical  or  hori- 
zontal pipe. 

(3)  The  pipe  should  have  a 
straight  run  of  at  least  8 pipe  diam- 
eters preceding  the  leading  side  of 
the  nozzle  plug.  That  is,  if  the 
inside  pipe  diameter  is  6 in.,  the 
pipe  should  be  straight  for  at  least 
48  in.  See  Fig.  3.  It  is  evident  that 
a straight  run  greater  than  8 pipe 
diameters  will  be  satisfactory.

Note. — For  exception  as  to  boiler 
outlets  and  reducers  near  elbows, 
see  Figs.  14,  15  and  17.  For  water 
meters,  Fig.  16.

) 


Drilling  and  Tapping 

(4)  Drill  and  tap  the  main  hori- 
zontally for  air  or  steam,  and  in  line 
with  the  pipe  diameter  for  a 3^-in., 

in.,  or  1-in.  pipe  thread,  depend- 
ing upon  the  size  of  nozzle  plug 
to  be  used.  See  Figs.  29  and  30. 
With  a nozzle  plug  screwed  in  tightly 
the  distance  from  the  outside  of  the 
pipe  to  the  first  flange  on  the  plug 
should  be  approximately  yq  in. 
Drill  and  tap  the  main  for  a pressure 
gauge  and  a thermometer  well,  if 
necessary.  The  pressure  gauge  may 
be  tapped  into  the  main  ahead  of 
the  nozzle  plug  but  the  thermometer 
well  must  be  inserted  beyond  the 
nozzle  plug. 

When  drilling  and  tapping  the 
main  for  the  insertion  of  the  nozzle 
plug,  pressure  gauge  or  thermometer 
well,  care  should  be  taken  that  no 
chips  get  inside  of  the  main  and 
thence  into  an  engine  or  turbine,  or 
other  apparatus.  A slight  pressure 
inside  the  pipe  will  often  prevent 
this  from  occurring.  In  certain 
cases  it  may  be  advantageous  to 
remove  the  section  of  pipe  before 
drilling  and  tapping. 

For  a vertical  pipe,  the  flanges 
below  the  point  of  , drilling  may  be 
slightly  spread  and  the  chips  caught 
on  a thin  sheet  of  metal  inserted 
between  the  flanges. 

Obtaining  Exact  Diameter  of  Pipe 

(5)  After  the  hole  in  the  main  is 
drilled  and  tapped  to  receive  the 
plug,  the  inner  diameter  of  the  pipe 
should  be  carefully  measured,  as 
pipes  vary  considerably  from  the 
rated  diameters. 


86503A-10  Recording  and  Integrating  Flow  Meters 


Fig.  3 shows  a convenient  form  of 
gauge  for  measuring  the  internal 
diameter  of  the  pipe.  It  is  made 
from  a piece  of  brass  about  % in. 
wide  and  ye  in*  thick.  Its  length  will 
depend  upon  the  diameter  of  the 
pipe  to  be  measured.  Make  the 
distance  marked  “pipe  diameter” 
a little  longer  than  the  internal 
diameter  of  the  pipe  and  then  file 
off  theN  L-shaped  projection  until 
the  gauge  just  fits  the  pipe  when 
inserted  in  the  hole  drilled  for  the 
nozzle  plug.  This  eliminates  any 
effect  of  the  burr  caused  by 
drilling. 

(6)  Mains  are  often  not  exactly 
circular  and  if  very  accurate  results 
are  desired  from  the  meter,  and  it  is 
not  possible  to  measure  the  average 
internal  diameter  at  the  nozzle  plug, 
measure  several  external  diameters 
of  the  pipe  where  the  nozzle  plug  is 
inserted. 

Compare  these  measurements  with 
the  external  diameter  in  line  with  the 
nozzle  plug. 

If  these  outside  diameters  vary, 
calculate  their  respective  internal 
diameters  and  take  the  mean  as  the 
actual  internal  diameter. 


Setting  the  Plug 

(7)  Screw  the  nozzle  plug  into 
the  main,  noting  that  when  the  plug 
is  made  tight  the  arrow  on  the  plug 
must  point  in  the  direction  of  flow. 
Fig.  4 shows  the  four  possible  posi- 
tions for  plug.

Connecting  the  Nipples  and  Valves 


(8)  Screw  the  two  bent  sections 

of  pipe  into  the  two  holes  marked 
L and  T which  lie  in  the  same  hori- 
zontal plane  and  which.;  are  marked 
X in  Fig.  4.  ^ .. 

(9)  Close  the  other  holes  L and 
T on  the  nozzle  plug  with  the  two 
long  plugs. 


(10)  Screw  the  two  valves  on  to 
the  two  bent  sections  of  pipe. 

(11)  Screw  the  nipple!  into  the 
valves. 


(12)  And  lastly  screw  the  reser- 
voirs on  to  the  nipples. 

(13)  Cylindrical  reservoirs  must 
be  located  with  the  ends  marked 
“TOP”  at  the  top. 

(14)  Take  care  that  the  bent 
pipes  and  reservoirs  for  air  or  steam 
meters  are  level  in  all  directions. 
Determine  this  by  using  a straight 
edge  and  spirit  level.  For  water 
flow  meters  the  leveling  of  these 
pipes  is  unnecessary. 


Inspection  of  Plug  Installation 

(15)  Be  sure  the  arrow  on  the 
head  of  the  plug  points  in  the 
direction  of  flow  in  the  main.

(16)  The  correct  size  of  pipe  or 
reducer,  for  which  a nozzle  plug  is 
designed,  is  stamped  upon  the  head 
of  the  plug. 


(17)  For  steam  flow  the  nozzle 
plug  and  valve  stems  must  be  level. 
See  that  the  reservoirs  are  level,  one 
with  the  other  across  their  tops. 


(18)  The  extra  holes  L and  T 
must  be  plugged. 


(19)  The  reservoirs,  used  for 
steam  flow,  must  have  the  ends 
marked  “TOP”  at  the  top. 


(20)  Valve  stems  must  be  packed, 
glands  secure  and  allow  absolutely 
no  leaks  at  joints,  valve  stems,  or 
valves. 


(20)

2.  LOCATION  OF  METER 

(21)  The  meter  may  be  located  in 
any  convenient  place  not  subject  to 
severe  vibration  and  where  it  can  be 
protected  from  damage  and  from 
freezing.  The  distance  between  the 
meter  and  nozzle  plug  is  immaterial. 
Meters  800  feet  from  plug  are  in 
operation.  The  air  and  the  water 
meter  may  be  located  either  above 
or  below  the  nozzle  plug.  For 
locating  the  steam  meter  above 
nozzle  plug,  special  rules  for  piping 
must  be  followed.  Refer  to  Fig.  19. 

The  horizontal  piping  between 
plug  and  meter  must*  slope  toward 
the  meter  to  prevent  pocketing. 

3.  PIPING  BETWEEN  NOZZLE 
PLUG  AND  METER 

(22)  Standard  iron  pipe  is 

recommended. 

(23)  Provide  piping  that  will 
connect  the  sides  L and  T at  the 
nozzle  plug  to  the  respective  sides 
L and  T of  the  meter. 

(24)  Use  pipe  cement  sparingly 
and  on  male  threads  only. 

(25)  Cut  all  thread  joints  long 
and  clean. 

(26)  Make  up  all  thread  joints 
extra  tight. 

(27)  Do  not  lag  the  pipes  L and 
T but  locate  them  where  freezing 
temperature  cannot  reach  them. 

(28)  Properly  support  the  piping 
by  pipe  hangers  where  necessary, 
for  protection  against  displacement 
or  sagging. 


Recording  and  Integrating  Flow  Meters  86503 A-15 


(29)  Blow  out  the  pipes  thor- 
oughly by  opening  wide  the  valves 
L and  T under  full  pressure. 

(30)  Do  this  before  connecting 
the  pipes  to  the  meter. 

(31)  Let  the  steam  blow  for 
three  minutes  during  which  time 
rap  the  pipes  to  dislodge  all  loose 
scale  or  dirt. 


4.  INSTALLING  THE  METER 

(32)  Provide  a rigid  table,  shelf 
or  bracket,  with  top  surface  level, 
for  the  meter. 

(33)  A universal  wall  bracket 
can  be  supplied  for  mounting  meters 
on  boiler  fronts  or  other  places. 


Description  of  the  Meter 

The  body  of  the  meter  is  of  cast 
iron.  The  form  illustrated  in  Fig. 
5 is  used  for  all  types  here  described. 
Fig.  8 shows  an  interior  view  of  the 
meter  body,  with  the  internal  mech- 
anism in  place  and  part  of  the 
casting  cut  away.  The  internal 
mechanism  is  shown  removed  from 
the  meter  in  Fig.  9. 

Refer  to  sectional  view  Fig.  7. 
The  base  of  the  meter  is  about  half 
filled  with  mercury,  which  supports 
the  iron  float  in  the  tube.  In  meters 
for  steam  or  water,  it  is  necessary 
to  fill  the  meter  and  pipes  above  the 
mercury  surface  with  water.  The 
water  priming  must  not  be  done  in  the 
case  of  air  meters.  The  pressure  dif- 
ferential, due  to  the  flow  of  the  stream 
being  metered,  displaces  the  mercury

and  thereby  the  internal  float  mech- 
anism which  constitutes  the  prime 
moving  element  of  the  meter.  This 
pressure  difference  is  conveyed  from 
the  nozzle  plug  to  the  meter  by  the 
two  pipes  L and  T. 

For  a given  rate  of  flow,  the 
mercury  and  the  float  will  be 
deflected  a definite  distance  up  the 
tube.  The  float  is  geared  by  rack 
and  pinion  to  a cross  shaft  which 
carries  a permanent  .U-shaped  mag- 
net as  shown.  The  magnet  poles 
face  toward  the  copper  cap  bolted 
over  the  opening  in  the  meter  body. 
It  is  well  to  see  that  all  bolts  holding 
the  copper  cap  and  the  meter  base 
are  tight  so  there  will  be  no  leakage 
at  either  place.  The  external  mech- 
anism of  the  meter  has  a shaft  in 
axial  alignment  with  the  inner  shaft 
and  carrying  a similar  magnet. 
Thus,  magnetism  is  used  to  trans- 
mit the  motion  from  interior  to 
exterior  of  meter  body.  The  outer 
shaft  turns  synchronously  with  the 
inner  shaft,  moving  the  indicating 
needle,  recording  pen  and  integrat- 
ing cam.  The  outer  case  of  the 
meter  contains  the  record  chart  and 
driving  clock,  also  the  indicating 
scale,  the  indicating  needle,  the 
recording  pen  and  integrating  attach- 
ment. 

To  Assemble  the  Meter 

(34)  Remove  the  meter  body 
from  the  packing  case  and  set  it  up- 
right with  the  cover  plate  removed. 

Carefully  remove  the  external 
mechanism,  complete  with  recording 
pens  and  brass  jigs  from  its  box. 
Place  it  inside  the  meter  case  over 


86503A-22  Recording  and  Integrating  Flow  Meters 


the  two  dowel  pins  and  fasten  it 
firmly  with  the  three  cap  screws. 
Carefully  remove  the  pieces  of  felt 
from  under  the  indicating  needle, 
and  the  felt  and  string  from  the 
integrating  attachment,  if  the  meter 
is  equipped  with  such  a device. 
Mount  one  of  the  glass  pens  on  the 
pen  arm. 


Mercury  Priming 

(35)  Remove  the  cover  plate, 
open  crossover  valve  and  fill  the 
meter  with  clean  water. 


(36)  Then  pour  into  the  casting 
the  10  pounds  of  mercury  shipped 
with  the  meter. 

Remove  the  internal  mechanism 
and  sleeve  from  its  box,  and  lower 
the  sleeve  into  position  in  the  meter 
body  so  that  the  hole  in  the  bottom 
of  the  sleeve  fits  over  the  correspond- 
ing pin  in  the  base  of  the  meter. 
Then  fasten  sleeve  in  position  by  the 
small  screw  and  washer  at  the  top 
of  the  sleeve  rod. 

(37)  . Examine  internal  mecha- 
nism, see  that  the  magnet  clears  the 
frame  ^ in.  and  that  it  will  rotate 
freely  when  float  is  lifted. 


Recording  and  Integrating  Flow  Meters  86503 A—  23 


(38)  Lower  the  float  of  the  inter- 
nal mechanism  carefully  into  the  hole 
in  the  sleeve  so  that  the  float  rests 
on  the  mercury,  and  then  fasten  the 
internal  bracket  in  position  with  the 
two  screws. 


(39)  To  change  the  internal 
mechanism,  proceed  as  follows:  Re- 
move cover  plate  from  meter.  Take 
out  the  two  screws  and  lift  out  the 
internal  mechanism.  Remove  water 
from  the  meter  until  the  screw  hold- 
ing the  sleeve  is  exposed.  This 
screw  is  about  6 in.  below  the  cover 
plate.  Remove  this  screw  and  pull 
out  the  sleeve.  Install  new  sleeve, 
taking  care  that  the  hole  engages 
with  the  pin  at  the  bottom  of  the 
meter.  This  will  bring  the  rod  pro- 
jecting above  the  sleeve  opposite 
the  screw  hole.  Rotate  the  swivel 
handle  at  the  top  of  this  rod  until  it 
lies  flat  against  the  inside  of  the 
meter.  Fasten  the  sleeve  in  position 
with  the  screw.  To  change  the  shaft 
of  internal  mechanism,  loosen  screws 
holding  the  rods  supporting  idler 
pulley  frame,  and  move  this  frame 
away  from  the  rack.  Remove  pivot 
support,  being  very  careful  not  to 
damage  pivot  points.  Remove  shaft 
and  magnet.  Install  magnet  on  new 
shaft  and  then  install  the  new  shaft 
in  the  frame.  Pull  out  the  small 
pin  at  the  top  of  the  circular  rack. 
Replace  rack  and  float  by  new  ones 
having  the  same  number  as  the  new 
sleeve  and  gear.  Adjust  idler  pulley 
frame  so  that  the  circular  rack  will 
not  bind  with  the  pinion  at  any  point 
of  its  travel.  Install  internal  mech- 
anism in  meter  and  note  position  of 
recording  pen  or  indicating  needle. 


86503A-84  Recording  and  Integrating  Flow  Meters 


If  necessary,  remove  the  internal 
mechanism  and  adjust  the  magnet 
so  that  the  needle  and  pen  can  be 
brought  to  zero  and  yet  travel  over 
the  full  scale.  Put  in  the  screws 
holding  the  internal  mechanism  and 
fill  the  meter  with  water.  Put  on 
cover  plate,  and  fasten  tightly. 

(40)  The  outer  magnet,  gear  and 
clock  can  be  inspected  if  plate  D 
(Fig.  7)  is  removed  by  unscrewing 
the  three  supporting  screws. 

Zero  Setting 

Unpack  the  indicating  scale  plate 
and  place  it  in  position  in  the  meter 
case,  passing  the  large  slot  carefully 
over  the  indicating  needle.  Then 
rotate  the  scale  to  its  proper  position. 

(41)  With  meter  level  and  full  of 
water  but  still  disconnected  from 
piping,  the  cross  over  valve  open  and 
cover  plate  off,  the  indicator  needle 
and  recording  pen  can  be  adjusted 
to  zero. 

(43)  Move  the  indicating  scale 
so  that  the  nut  which  holds  the  pen 
is  visible. 

(44)  Loosen  this  nut  and  adjust 
recording  pen  to  read  zero  on  the 
chart. 

(45)  Tighten  the  nut. 

(46)  Then  adjust  the  indicating 
scale  slightly  so  that  the  indicator 
reads  zero. 

(47)  If  the  indicator  cannot  be 
brought  to  zero  by  shifting  the  dial 
slightly,  remove  the  internal  mecha- 
nism and  rotate  the  magnet  to  the 
right  or  left  as  necessary. 


Recording  and  Integrating  Flow  Meters  86503 A-25 


(48)  In  making  adjustments, 
avoid  shifting  the  magnet  endwise 
on  shaft.  The  magnet  must  have 
^ in.  clearance  on  all  sides. 


If  the  pen  and  indicating  needle 
do  not  come  back  to  zero,  there  may 
be  excessive  pen  pressure  on  the 
paper  chart,  too  great  pressure 
between  the  integrating  record  wheel 
and  the  paper,  or  there  may  be 
excessive  bearing  friction  in  the  pivot 
bearings  supporting  the  integrating 
mechanism. 

(49)  When  the  magnet  is  ad- 
justed so  that  the  indicating  scale 
and  pen  rest  at  zero'  and  can  also  be 
given  their  full  range  of  movement 
by  raising  and  lowering  the  float 
rack  with  the  fingers,  the  meter  is 
ready  to  close. 

(50)  Before  replacing  the  cover 
plate,  completely  fill  the  meter  with 
water. 

(51)  Then  replace  cover  plate 
and  fasten  pressure  tight. 

Remove  the  plug  from  top  of  cap 
on  cover  plate,  and  completely  fill 
this  cap  with  water.  Then  replace 
this  plug. 


Note. — Air  meters  are  not  primed 
with  water. 


Connecting  and  Priming  the  Meter 
Pipes 

(52)  Connect  the  meter  to  the 
two  pipes  leading  to  the  reservoirs. 


86503 A-26  Recording  and  Integrating  Flow  Meters 

Be  sure  that  the  pipe  L of  the  meter 
is  connected  to  the  L side  of  the  plug, 
and  the  other  side  T to  T.  See 
Fig.  63. 


(53)  When  filling  with  water  all 
air  must  be  removed  from  the  pipes 
L and  T without  overdeflecting  the 
mercury. 


(54)  This  is  easily  done  by 
watching  the  recording  pen. 


Proceed  as  follows  for  steam: 

(55)  With  pressure  in  the  main 
pipe  open  cross  over  valve. 


(57)  Open  the  two  blow  off 
valves  and  the  meter  valves,  Fig.  6. 


(58)  Carefully  open  the  valves  L 
and  T at  the  nozzle  plug,  about 
turn  of  the  stems,  so  that  steam  will 
slowly  drive  all  air  out  of  both  pipes 
and  flow  out  of  the  blow  off  valves, 
thus  preventing  re-entrance  of  air. 

(59)  While  the  steam  is  flowing 
out,  close  both  blow  off  valves. 


(60)  Close  valve  T and  wait 
until  the  pipes  cool  sufficiently  to 
show  that  the  steam  flowing  in 
slowly  through  valve  L has  con- 
densed and  filled  both  pipes  with 
water. 


(61)  Then  open  wide  valve  L.

(62)  Then  close  cross  over  valve. 

(63)  And  finally  open  valve  T. 

(64)  The  meter  will  then  register 
the  flow. 


(65)  It  is  essential  for  accurate 
operation  of  either  the  steam  or 
water  meter,  that  all  pipes  up  to  and 
including  the  reservoirs  be  com- 
pletely full  of  water.  Any  air  which 
may  have  been  trapped  in  either  the 
meter  or  piping  by  improper  filling 
will  cause  the  meter  to  indicate 
incorrectly. 


(66)  All  joints  in  the  meter  pipes, 
nozzle  plug,  valves,  etc.,  must  be 
absolutely  tight.  If  there  are  any 
leaks,  no  matter  how  small,  the 
meter  will  not  indicate  correctly. 


SPECIAL  INFORMATION  FURNISHED 

If  it  is  not  possible  to  locate  the  nozzle  plug  or  meter  according  to 
the  rules  given,  a sketch  showing  the  plan  and  elevation  with  dimen- 
sions of  the  particular  piping  should  be  forwarded  to  nearest  office 
of  the  General  Electric  Company  (see  list  on  last  page)  who  will 
advise  the  best  location  for  the  nozzle  plug  and  meter. 


INSPECTION  OF  COMPLETED  METER  INSTALLATION 

With  pressure  on  the  meter  and  no  flow  in  the  main,  valves  L and 
T open  and  cross  over  valve  closed,  the  following  must  be  true  if  the 
meter  is  in  proper  condition: 

1.  Absolutely  no  leaks. 

2.  The  meter  level. 

3.  The  proper  pipe  connections. 

4.  The  meter  registering  zero  as  first  adjusted. 

5.  The  meter  piping  cold. 


86503 A-28  Recording  and  Integrating  Flow  Meters 


5.  OPERATING,  ADJUSTMENT  AND  READING 
To  Cut  in  the  Meter 

Always  operate  the  valves  in  the  following  order  when  starting  a 
meter: 

First  open  the  cross  over  valve.  Then  open  the  valve  L.  Then 
close  the  cross  over  valve  and  open  tho  valve  T.  The  meter  will  then 
register  the  flow. 

To  Cut  Out  the  Meter 

Close  valves  L and  T and  open  cross  over  valve  in  the  order 
given. 

To  Check  Zero 

Cut  out  the  meter  by  closing  valves  L and  T and  opening  cross 
over  valve.  The  indicating  needle  will  then  read  zero. 

Caution 

When  steam  is  off  the  main  line,  the  meter  will  not  necessarily 
read  zero  unless  the  cross  over  valve  is  open. 

To  Read  the  Indicating-Recording  Meters,  Types  FS-4,  FA-4  and  FW-4 

The  conditions  for  which  the  meter  is  calibrated  will  be  found  on 
the  name  plate.  In  addition  to  the  serial  number,  type,  etc.,  the  name 
plate  gives  the  pipe  diameter,  pressure,  the  kind  and  the  quality  of  the 
fluid  for  which  the  indicating  scale  is  calibrated.  It  shows  in  what 
units  the  meter  is  calibrated.  It  also  gives  the  multiplying  constant 
to  be  applied  to  all  readings  of ' indicating  scale,  recording  chart  and 
integrating  attachment. 

As  an  example,  one  of  the  numerous  plates  is  illustrated  in  Fig.  10. 


Fig.  10.  FLOW  METER  NAME  PLATE 

It  will  be  seen  that  this  plate  is  for  a Type  FS-4  meter,  calibrated 
to  measure  steam  at  150  pounds  gauge  superheated  5 deg.  F.,  when 
flowing  through  a pipe  in.  in  diameter.  The  calibration  is  in  boiler 
horse  power,  the  basis  being  30  pounds  per  hour.  The  reading  of  the 


Recording  and  Integrating  Flow  Meters  86503 A-29 

indicating  scale  is  to  be  multiplied  by  10  to  obtain  the  boiler  horse 
power.  The  recording  scale  reading  is  to  be  multiplied  by  119  to 
obtain  the  boiler  horse  power.  Now  if  the  indicating  needle  registers 
50,  this  figure  multiplied  by  the  constant  10  for  the  indicator,  gives 
500  as  the  boiler  h.p.  and  if  the  pen  registers  4.2  this  figure,  multiplied 
by  the  constant  119  also  gives  500  as  the  boiler  h.p. 

To  Read  the  Recording  Meter,  Type  F 

To  read  the  Type  F meter,  the  operator  must  determine  the 
multiplying  constants  from  the  general  instructions  here  furnished. 

The  charts  are  ruled  either  for  the  nozzle  plug,  or  for  the  orifice 
tube  and  are  marked  accordingly. 

The  meter  can  be  equipped  with  any  one  of  seven  sizes  of  internal 
mechanisms,  floats  and  sleeves. 

The  various  sizes  have  been  provided  to  secure  a good  location 
on  the  chart  for  the  pen  line,  and  thereby  obtain  accurate  measure- 
ments under  widely  varying  conditions.  To  illustrate,  when  the 
velocity  of  flow  is  low,  mechanism  No.  1,  which  has  a large  diameter 
float  and  small  diameter  gear,  should  be  used.  If  the  velocity  of  flow 
is  high  use  mechanism  No.  7,  which  has  a float  small  in  diameter  and 
a large  diameter  gear.  For  intermediate  conditions  use  the  most  suit- 
able mechanism. 

To  enable  the  user  of  Type  F meters  to  select  the  mechanism 
most  suitable  for  any  given  conditions,  the  following  multipliers  can  be 
used  to  determine  the  range  limit  of  the  meter  when  equipped  with 
any  one  of  the  several  mechanisms.  These  multipliers  must  be  used 
in  connection  with  the  flow  tables  in  the  back  of  this  book  as  the 


maximum  flow  figures  in  the  flow  tables  are  for  meters  equipped  with 
internal  mechanism  No.  7.

Note  that  it  is  necessary  to  reduce  the  float  tube  diameter  by 
inserting  the  proper  sleeve  when  using  any  one  of  mechanisms  1 to  7 
inclusive. 

The  multiplying  constant  for  the  pen  readings  is  derived  from  the 
following  factors: 


8650SA-30  Recording  and  Integrating  Flow  Meters 

1.  The  internal  diameter  of  the  pipe,  pipe  reducer,  or  the  orifice 
tube  dimensions. 

2.  The  pressure  of  the  fluid. 

3.  The  quality  of  the  fluid. 

4.  The  internal  mechanism,  according  to  number  of  same. 

5.  The  type  of  nozzle  plug,  normal  or  high  velocity. 

To  enable  the  operator  to  obtain  the  constant  for  a given  com- 
bination of  these  variable  factors,  the  diagrams  No.  11-B,  12-B  and 
13-B  for  nozzle  plugs,  for  steam,  air  and  water  have  been 
prepared. 

Diagrams  No.  14,  15  and  16  have  been  prepared  for  orifice  tubes. 

It  will  be  noted  that  the  constants  are  such  that  the  readings 
obtained  will  be  in  the  units  most  appropriate  for  the  fluid  being 
metered. 

Factors  for  certain  other  fluids  than  the  above  can  be  furnished. 

To  use  the  diagrams,  assume  for  the  purpose  of  illustration  that 
it  is  desired  to  find  the  constant  for  the  following  combination: 

1.  83^8  in.  internal  diameter  of  main. 

2.  170  lb.  G.  steam  pressure. 

3.  100  deg.  F.  superheat. 

4.  Internal  mechanism  No.  6. 

5.  Normal  velocity  nozzle  plug. 

Refer  to  diagram  11-B  (for  steam).  Read  up  from  83d*  in. 
measured  internal  pipe  diameter  to  intersection  with  curve  1.  From 
this  point  read  to  the  scale  of  curve  1 and  determine  the  value  of 
Ki  —7350. 


Read  upward  from  the  quality  scale  at  100  deg.  F.  superheat  to 
curve  2,  and  thence  to  the  left  to  obtain  K2  =0.927. 

Read  upward  from  170  on  the  pressure  scale  to  curve  3,  and 
thence  to  the  left  to  obtain  K3  = 1.055.  From  the  tabulation  obtain 
Kcp  = 1.00  for  mechanism^  No.  6.  For  the  normal  velocity  nozzle 
plug  K4  = 1.  (For  the  high  velocity  nozzle  plug  K4  = 1.5.) 

Multiply  Ki,  K-2,  K3,  K4  and  Kcp  together  and  obtain  the  multi- 
plying constant,  thus:  7350X0.927X1.055X1X1=7298.  To  use  the 
constant  assume  the  pen  is  registering  with  line  6 of  the  chart.  Then 
the  constant  7298X6=43,788 — the  rate  of  flow  in  pounds  of  steam 
per  hour.

The  Flow  Meter  Planimeter 

Since  the  chart  divisions  are  not  uniformly  spaced,  an  ordinary 
polar  planimeter  is  not  satisfactory  for  the  determination  of  the  average 
pen  reading. 

To  obtain  from  the  recording  chart  curve  the  total  quantity  of 
fluid  delivered  during  an  interval  of  time,  the  flow  line  must  be  inte- 
grated with  a flow  meter  planimeter  unless  the  meter  is  provided  with 
an  integrating  attachment.  (See  Fig.  11.) 

The  planimeter  for  the  charts  is  a special  form  of  instrument. 
The  instrument  has  separate  cams  for  planimetering  charts  made  with 
nozzle  plug  and  with  orifice  tube. 

The  integrating  device  has  separate  cams  for  nozzle  plug  and 
orifice  tube  service. 

Complete  instructions  for  using  the  planimeter  are  furnished 
herewith. 

RADIAL  FLOW  METER  PLANIMETER,  TYPE  P-2 

The  radial  flow  meter  planimeter,  which  includes  a planimeter, 
case  and  base  plate,  is  a device  manufactured  by  the  General  Electric 
Company,  Schenectady,  N.  Y.,  to  integrate  the  flow  line  on  the  charts 
taken  by  G-E  recording  flow  meters,  Types  FS-4,  FA-4,  FW-4  and  F. 

Chart 

Place  the  chart  on  the  base  plate.  Replace  the  circular  weight 
for  holding  the  paper  down. 

Cams 

Different  cams  are  used  depending  upon  whether  the  chart  is 
from  a meter  connected  to  a nozzle  plug  or  orifice  tube. 


86503 A-32  Recording  and  Integrating  Flow  Meters 

When  two  cams  are  supplied,  care  must  be  taken  that  the  correct 
cam  is  used. 

Each  cam  is  complete  with  a tracing  arm  and  point.  The  one  for 
use  with  nozzle  plug  is  marked  N2  and  the  one  for  use  with  orifice 
tube  is  marked  02. 

To  Change  Cams 

To  remove  a cam,  loosen  the  set  screw  at  the  bottom  of  the  tracing 
arm  and  then  disconnect  the  spring. 

To  insert  a cam,  first  place  the  spring  on  the  post,  then  place  the 
cam  in  position,  adjust  the  pivot,  and  tighten  the  set  screw. 

To  Integrate 

Mount  the  planimeter  upon  the  bed  plate.  Set  the  tracing  pointer 
on  the  zero  flow  line  of  the  chart.  Move  the  tracing  pointer  from  the 
zero  flow  line  on  a constant  time  line  to  the  flow  line  to  be  integrated. 
Move  this  tracing  pointer  over  the  flow  line  as  far  as  it  is  desired  to 
integrate  and  lastly  move  the  tracing  pointer  back  to  the  zero  flow 
line  on  a constant  time  line. 

Planimeter  Reading 

The  difference  between  the  initial  and  final  readings  of  the  dials 
is  the  net  planimeter  reading. 

To  Read  the  Planimeter 

One  complete  revolution  of  the  friction  wheel  or  1/10  revolution 
of  the  large  wheel  is  equivalent  to  10. 

Therefore,  if  the  pointer  on  the  large  wheel  registers  between  4 
and  5,  and  the  pointer  on  the  friction  wheel  registers  midway  between 
2 and  3,  the  planimeter  reading  is  42.5. 

If  the  initial  reading  was  11.3  and  the  final  reading  is  42.5,  the  net 
planimeter  reading  is  42.5  — 11.3  or  31.2.

The  planimeter  equipment  comprises  a circular  plate  for  holding 
the  chart  and  pivoting  the  instrument. 

Separate  cams,  which  are  interchangeable,  are  necessary  for 
using  the  meter  on  nozzle  plug  and  orifice  tube  charts. 

A jig  is  furnished  with  each  planimeter  for  checking  up  the  instru- 
ment. The  following  table  shows  the  net  planimeter  readings  which 
should  be  obtained  from  the  various  chart  lines  or  by  using  this  jig.

The  Integrating  Attachment 

The  integrating  attachment  can  be  applied  to  any  of  these  record- 
ing meters.  The  mechanism  comprises  figured  dials,  having  indicating 
needles  that  are  operated  by  a planimeter  wheel,  which  in  turn  is  driven 
by  the  chart.  The  planimeter  wheel  is  shifted  for  changing  flow  values 
by  a cam  attached  to  the  pen  shaft.  (See  Fig.  12.) 


Recording  and  Integrating  Flow  Meters  86503 A-35 

To  Assemble  the  Integrating  Attachment 

First,  rotate  the  indicating  scale  so  that  the  nut  at  the  lower 
left-hand  side  is  visible.  Loosen  this  nut.  Place  the  sector 
supporting  the  cam  and  recording  pen  on  this  shaft,  then  tighten 
nut  so  that  the  recording  pen  reads  zero  at  the  same  time  the 
indicating  pointer  reads  zero.  Next,  mount  the  integrating  device 
on  the  pivot  points  at  the  lower  right-hand  side  of  the  chart.  This 
device  should  be  in  perfect  balance  about  these  pivot  points.  The 
friction  wheel  on  the  dial  mechanism  should  now  rest  firmly  against 
the  paper  with  the  knife  edge  between  the  two  cams.  When  in  this 
position,  the  angle  of  the  record  wheel  will  be  changed  relative  to  the 
paper  travel  whenever  the  flow,  as  indicated  by  the  recording  pen  and 
indicating  needle,  is  changed.  A spring  is  provided  with  an  adjustable 


Fig.  12.  G-E  INDICATING-RECORDING,  INTEGRATING 
FLOW  METER  WITH  LAMP 

nut  so  as  to  vary  the  tension  of  the  friction  wheel  on  the  paper.  If 
there  is  any  vibration  of  the  meter,  the  spring  should  be  adjusted  so  as 
to  hold  the  friction  wheel  firmly  against  the  paper.  With  the  indicating 
needle  and  recording  pen  on  zero,  the  integrating  device  should  also 
read  zero.  This  can  readily  be  tried  out  by  revolving  the  paper  chart 
by  hand.  The  friction  wheel  should  not  rotate  at  zero  flow. 


86503A-36  Recording  and  Integrating  Flow  Meters 

If  it  is  necessary  to  increase  the  readings  of  the  integrating  device, 
move  the  lever  carrying  the  small  knife  edge  either  down,  to  the  left, 
or  both. 

To  Read  the  Dials 

One  complete  revolution  of  right-hand  pointer  or  1/10  revolution 
of  middle  pointer  is  equivalent  to  10. 

Therefore,  if  the  pointer  on  the  middle  dial  registers  between  4 
and  5,  and  the  pointer  on  the  right-hand  dial  registers  midway  between 
2 and  3,  the  integrating  dial  reading  is  42.5. 

If  the  initial  reading  was  11.3  and  the  final  reading  is  42.5,  the  net 
dial  reading  is  42.5  — 11.3  or  31.2. 

Read  the  dials  from  right  to  left. 

To  Check  Integrating  Attachment 

If  it  is  desired  to  check  the  accuracy  at  any  time  fasten  the  meter 
mechanism  in  position  so  that  the  recording  pen  reads  at  the  3,  6 
or  9 line,  using  the  brass  jig.  Then,  by  revolving  the  paper  chart,  the 
dial  reading  can  be  observed. 

The  following  table  gives  the  correct  net  dial  reading  of  the  dials 
for  one  complete  revolution  of  the  paper  chart.

A jig  is  furnished  for  setting  the  pivot  points  on  which  the  inte- 
grating mechanism  swings.  This  will  be  needed  if,  for  any  reason,  this 
arm  has  been  removed.  To  use  this  jig,  remove  the  sector  supporting 
the  cam  and  recording  pen.  Remove  the  paper  chart,  also  the  54-in. 
center  piece  on  which  it  rests.  Place  the  Y^-'vn.  hole  of  the  jig  on  the 
clock  shaft  and  the  34-in.  hole  on  the  pen  shaft.  The  jig  must  rest 
securely  and  firmly  against  the  chart  plate.  Adjust  the  arm  carrying 
the  integrating  attachment  until  the  pivot  point  rests  exactly  at  the 
center  of  the  post  on  the  jig.  At  the  same  time  check  setting  of  pen  as 
follows:  Without  removing  jig,  place  the  sector  supporting  cam  and 

recording  pen  on  pen  shaft.  With  the  pen  point  registering  with  the 
center  punch  mark  in  the  jig,  the  pin  on  the  jig  should  lie  between  the 
two  cams  and  against  the  lower  cam.  In  other  words:  Raise  the  cam 
sector  so  that  there  is  no  clearance  between  the  pin  and  the  lower  cam. 


Recording  and  Integrating  Flow  Meters  86503 A-37 

The  pen  point  should  then  register  with  the  center  punch  mark  in  the 
jig.  If  the  pen  arm  has  been  twisted  so  the  pen  point  does  not  register, 
it  should  be  straightened.  It  is  seldom  necessary  to  loosen  the  screw 
holding  the  pen  arm  to  the  sector.  Then  reassemble  meter. 

If  the  clock  is  removed  for  cleaning,  it  should  be  relocated  as 
follows: 

Remove  the  chart  plate.  Place  one  3d* -in.  hole  in  the  jig  over  the 
pen  shaft.  Fasten  the  jig  in  position,  by  a screw  through  the  other 
3^-in.  hole  in  the  jig,  to  the  upper  post  which  supports  the  chart  plate. 
The  clock  shaft  must  register  with  the  %-in.  hole  in  the  jig.  Tighten 
the  four  screws  supporting  the  clock  frame  and  remove  the  jig. 

These  devices  are  carefully  adjusted  and  tested  at  the  factory  and 
should  operate  correctly  without  further  tests  or  adjustment. 

The  jig  spoken  of  above  is  merely  for  the  purpose  of  checking  up 
and  testing  these  devices,  if  this  is  desired.

Note:  The  friction  wheel  must  be  directly  in  line  with  the  pivot 

points.  To  check  this,  rotate  the  integrating  mechanism  about  the 
pivot  points.  The  friction  wheel  must  not  turn. 

Changing  Charts 

When  fastening  the  chart  in  place,  see  that  it  is  gripped  centrally 
and  that  its  edge  is  under  the  several  clips  around  the  circumference. 
Do  not  strain  the  clock  shafts  by  tightening  the  knurled  nut  too  much. 


Recording  and  Integrating  Flow  Meters  86503 A-39 

The  Clock 

The  clock  should  be  wound  every  24  hours.  Charts  can  be  fur- 
nished with  time  lines  suitable  for  a speed  of  one  revolution  in  either 
1,8,  12  or  24  hours.  Separate  clocks  can  be  furnished  for  the  several 
chart  speeds. 

6.  GENERAL  INFORMATION  AND  SUGGESTIONS 
Operation  of  Steam  Flow  Meters  on  Steady  Flow 

The  meters  are  carefully  calibrated  before  leaving  the  factory  to 
operate  under  steady  flow  conditions,  such  as  occur  when  supplying 
steam  to  steady  flow  turbines,  heating  systems,  manufacturing  pro- 
cesses, departments  of  a factory,  etc. 

Operation  of  Steam  Flow  Meters  on  Reciprocating  Engines  and  Pumps 

G-E  steam  flow  meters  will  not  accurately  measure  steam  supplied 
to  reciprocating  engines  and  pumps  if  the  flow  by  the  nozzle  plug,  pipe 
reducer  or  orifice  tube  is  periodically  intermittent.  The  flow  of  steam 
by  the  nozzle  plug,  pipe  reducer  or  orifice  tube  will  be  steady  and 
accurate  results  secured  from  the  meter,  if  sufficient  receiver  effect 
can  be  secured  between  the  engine  and  nozzle  plug,  pipe  reducer  or 
orifice  tube,  either  by  putting  in  a receiver  or  by  having  a run  of  steam 
pipe,  the  volume  of  which  will  act  as  a receiver,  and  be  sufficient  to 
supply  to  the  apparatus  the  instantaneous  amount  of  steam  needed. 
Operation  of  Water  Flow  Meters  on  Steady  Flow 

G-E  water  flow  meters  are  carefully  calibrated  before  leaving  the 
factory  to  operate  under  steady  flow  conditions,  such  as  occur  when 
measuring  water  flowing  by  gravity  or  delivered  by  centrifugal  pumps. 
Operation  of  Water  Flow  Meters  on  Reciprocating  Pumps 

The  meters  will  give  accurate  results  when  measuring  water 
delivered  by  reciprocating  pumps,  provided  the  water  flow  at  the  point 
of  installing  the  nozzle  plug,  pipe  reducer  or  orifice  tube  is  not  peri- 
odically intermittent.  This  condition  will  not  occur  if  the  reciprocating 
pumps  are  fitted  with  air  chambers  which  are  of  sufficient  capacity  to 
eliminate  pulsations  in  the  water  mains.  If  the  pump  should  not  have 
an  air  chamber,  one  must  be  installed  either  on  the  pump  itself  or  on 
the  water  main. 

Operation  of  Air  Flow  Meters  on  Steady  Flow 

All  G-E  air  flow  meters  are  carefully  calibrated  before  leaving 
the  factory  to  operate  under  steady  flow  conditions  such  as  occur  when 
measuring  air  delivered  by  rotary  compressors. 

Operation  of  Air  Flow  Meters  on  Reciprocating  Compressors 

The  meters  will  give  accurate  results  when  measuring  air  com- 
pressed by  reciprocating  as  well  as  rotary  compressors,  provided  the 


86503 A- 1+0  Recording  and  Integrating  Flow  Meters 

flow  at  the  point  of  installing  the  nozzle  plug,  pipe  reducer  or  orifice 
tube  is  not  periodically  intermittent.  This  condition  will  not  occur  if 
the  compressor  is  fitted  with  the  proper  size  and  kind  of  receiver. 

BASIS  OF  CALIBRATION 

Steam 

The  indicating  scale  figures  and  the  recording  chart  constants  are 
based  on  a given  combination  of  pipe  diameter,  quality  and  pressure. 

The  pressure  stamped  upon  the  name  plate  means  actual  steam 
pressure  in  the  main  at  the  nozzle  plug,  as  indicated  by  gauge  when  the 
barometric  pressure  is  29.92  in.  of  mercury,  or  14.7  lb.  absolute  pres- 
sure, unless  calibration  for  some  other  barometric  pressure  has  been 
requested. 

If  the  steam  pressure  in  the  main  is  appreciably  higher  than  the 
calibration  the  instrument  will  read  low  and  vice  versa.  For  example, 
assume  the  meter  to  be  calibrated  for  150  lb.  gauge  at  14.7  lb.  baro- 
metric pressure  (164.7  lb.  absolute).  Now  if  the  pressure  in  the  main 
is  high,  say  162.5  lb.  gauge  and  at  the  same  time  the  barometric  pres- 
sure is  low,  assume  12.2  lb.  (absolute  pressure  174.7),  the  meter  will 
read  3 per  cent  low.  If  the  steam  pressure  varies  equally  above  and 
below  the  normal  calibration  pressure,  which  is  not  unusual,  the  plus 
and  minus  errors  will,  of  course,  balance  each  other. 

Air 

The  volumetric  basis  of  calibration  for  all  air  flow  meters  is  cubic 
feet  per  minute  of  free  air  at  14.7  lb.  absolute  pressure  and  70  deg.  F. 
temperature. 

Water 

The  basis  of  calibration  of  all  water  meters  is  gallons  per  minute 
(U.S.  Standard,  231  cu.  in.)  at  a temperature  of  39.1  deg.  F. 

PIPE  REDUCERS  WITH  NORMAL  VELOCITY 
REDUCER  NOZZLE  PLUGS  FOR  STEAM, 

AIR  OR  WATER 

In  cases  where  the  velocity  of  flow  of  the  steam,  water  or  air  is 
too  low  to  be  accurately  measured  with  normal  velocity  nozzle  plugs, 
pipe  reducers  are  used.  This  reducer  consists  of  a metal  cylinder  with 
rounded  approach  inserted  between  and  held  in  place  by  the  two 
flanges  of  a pipe.  To  prevent  leakage  where  the  pipe  flange  surfaces 
are  rough,  a thin  gasket  on  each  side  of  the  reducer’s  flange  can  be  used. 

A reducer  nozzle  plug  is  screwed  into  the  pipe  and  projects  through 
a hole  in  the  pipe  reducer  itself.  It  extends  across  the  throat  of  the 
reducer  as  shown  in  Fig.  13. 


Recording  and  Integrating  Flow  Meters  86503 A-I^l 

No  appreciable  drop  in  pressure  is  produced  by  the  use  of  the 
pipe  reducer  because  the  velocity  of  flow  through  the  reducer  is  not 
raised  above  a value  considered  good  operating  practice  for  a pipe 
whose  diameter  is  the  same  as  the  diameter  of  the  reducer  outlet.  It 
may  be  installed  directly  in  sweeps  or  immediately  after  elbows,  valves 
or  tees  without  introducing  any  appreciable  error  in  the  meter  readings. 


Fig.  13.  PIPE  REDUCER  AND  NOZZLE  PLUG  INSTALLED  IN  A PIPE 

The  nozzle  plugs  used  with  pipe  reducers  differ  in  minor  respects 
from  both  the  normal  velocity  or  high  velocity  nozzle  plugs.  The 
same  pipe  reducers  can  be  used  with  any  type  of  G-E  flow  meter  for 
measuring  either  steam,  water  or  air. 

Installation  of  Pipe  Reducers 

The  pipe  reducer  is  furnished  blank,  no  flange  bolt  holes  being 
drilled  at  the  factory.  Neither  is  it  necessary  to  drill  the  reducer  so  as 
to  allow  the  flange  bolts  to  project  through  unless  desired,  as  it  can 
easily  be  cut  down  to  any  dimension  and  held  in  place  the  same  as  a

narrow  gasket.  It  may  be  used  with  Van  Stone  or  similar  flange  joints 
as  well  as  with  ordinary  screw  flanges. 

For  the  insertion  of  the  reducer,  a section  should  be  removed  and 
while  down  drilled  for  the  nozzle  plug.  After  the  pipe  reducer  has  been

drilled  or  cut  to  properly  fit  the  flanges,  it  can  be  placed,  together  with 
the  nozzle  plug,  in  the  section  of  pipe  removed  for  this  purpose  and  the 
whole  reassembled  in  the  pipe  line. 

The  hole  for  the  nozzle  plug  is  cut  in  the  reducer  at  the  factory. 
Its  location  for  various  sizes  is  indicated  by  the  distance  C,  Fig.  39. 

No  new  fittings  whatever  are  required  when  installing  pipe 
reducers.

drive  all  air  out  of  the  piping  and  appear  at  the  plug  holes  and  flow  out 
slowly  without  disturbing  the  mercury.  When  the  streams  flow  clear

without  air  bubbles,  close  both  blow  off  valves  tightly.  Then  open 
wide  the  valves  L and  T and  afterwards  close  cross  over  valve.  The 
meter  will  then  register  the  flow. 

Extra  Meter  Pipe  Valves 

When  the  meter  is  located  at  a considerable  distance  from  the 
nozzle  plug,  it  is  convenient  to  have  an  extra  valve  for  each  meter  pipe 
located  within  easy  reach.  The  proper  location  for  such  valves  is 
directly  above  the  cross  over  valve. 

PIPING  INSTRUCTIONS  FOR  LOCATING  METER 
ABOVE  THE  NOZZLE  PLUG 

When  a steam  meter  is  located  above  the  nozzle  plug,  the  pipes 
from  the  bottom  of  the  reservoirs  must  extend  downward  for  a distance 
of  about  six  feet  before  extending  upward  to  the  top  of  the  meter.  At 
the  high  point  in  the  piping  above  the  meter,  insert  reservoirs  and 
bleeder  valves  for  the  purpose  of  removing  any  air  that  may  accumu- 
late. See  Fig.  19. 

Before  starting  the  meter,  the  piping  should  be  filled  by  con- 
densation. 

Support  for  Reservoirs 

If  the  main  pipe  vibrates,  it  is  advisable  to  either  secure  the  main 
so  that  it  will  not  vibrate  at  the  point  where  the  nozzle  plug  is  inserted 
or  to  anchor  the  reservoirs  by  rigidly  connecting  them  to  the  main  with 
a suitable  pipe  hanger. 

Designating  Marks  on  Nozzle  Plugs 

In  addition  to  the  arrow  mark  for  setting  the  plug  to  flow  direc- 
tion, each  nozzle  plug  has'  either  the  pipe  diameter  or  the  pipe  and 
reducer  diameter,  for  which  it  is  intended,  stamped  in  figures  on  its 
head.  See  Fig.  20. 

The  type  of  plug  is  stamped  in  letters.  For  the  purpose  of  abbre- 
viation initial  letters  only  are  used.  Thus,  “NV”  is  used  for  the 
normal  velocity  plug,  “HV”  for  the  high  velocity  and  “NVR”  for 
the  normal  velocity  reducer  plug. 

The  marking  serves  to  designate  the  type  and  size  of  plug.  The 
location  of  the  marks  enables  an  inspection  check  of  the  plug  to  be 
made  after  it  is  inserted  in  a main. 

To  Clean  Nozzle  Plug 

If  a nozzle  plug  becomes  stopped  it  may  be  cleaned  by  blowing 
out  both  sides  with  steam  after  disconnecting  the  meter.  To  do  this, 


86503 A~46  Recording  and  Integrating  Flow  Meters 

close  the  reservoir  valves  L and  T.  Open  the  cross  over  valve,  and 
disconnect  the  unions,  then  open  the  valves  to  blow  steam  through  the 
nozzle  plug  and  piping. 

To  Clean  the  Piping 

Remove  the  meter  and  blow  out  steam. 


To  Blow  Out  Piping  and  Nozzle  Plug 

Because  there  is  a possibility  of  meter  piping  or  the  nozzle  plug 
becoming  filled  with  dirt  or  scale  the  meter  should  be  connected  as 
shown  in  Fig.  22.  To  blow  out  pipes  and  nozzle  plug,  open  the  cross 


Recording  and  Integrating  Flow  Meters  86503 A~47 


over  valve,  close  the  two  meter  valves  and  open  the  two  blow  off  valves. 
In  installations  where  the  water  is  very  bad  the  meter  piping  and 
nozzle  plug  should  be  thoroughly  blown  once  every  24  hours,  while 
in  the  usual  installation  once  every  two  weeks  is  sufficient.

Blow  Off  Pipes  for  Nozzle  Plug 

To  provide  a ready  means  for  cleaning  the  nozzle  plug  of  obstruc- 
tions where  the  fluid  is  always  impure,  blow  off  pipes  can  be  run  from 
the  extra  holes  L and  T in  the  nozzle  plug.  Provide  valves  for  these

pipes.  By  closing  the  reservoir  valves  and  opening  the  two  blow  off 
valves,  the  leading  and  trailing  sides  of  the  plug  can  be  blown  clean  as 
frequently  as  necessary. 

Close  the  blow  off  valves  before  cutting  the  meter  in.

(FOR  STEAM  OR  WATER) 

Before  starting  to  test  a meter  note  the  number  of  its  internal 
mechanism. 

When  prepared  for  test  the  meter  must  contain  the  proper  amoun 
of  mercury  and  water,  and  register  zero. 

If  the  meter  is  already  in  service  its  piping  need  not  be  dis- 
connected. The  illustration,  Fig.  22,  shows  a method  of  testing  with-

86503 A-52  Recording  and  Integrating  Flow  Meters 

The  figures  in  the  following  tabulation  are  for  testing  either  the 
steam  or  water  flow  meter  when  calibrated  for  the  nozzle  plug  at  the 
3,  6 and  9 lines  on  the  chart. 

The  deflection  of  the  indicator  needle  can  be  tested  at  the  same 
operation,  as  the  scale  is  provided  with  three  marks  corresponding 
to  the  3,  6 and  9 lines  of  the  chart.

TABLE  OF  WATER  COLUMN  ELEVATIONS 

The  tabulation  gives  water  column  figures  for  testing  meters  with 
the  seven  internal  mechanisms. 

The  different  mechanisms  are  numbered  from  1 to  7,  the  proper 
number  being  stamped  on  the  top  of  the  float,  on  the  gear  of  each 
internal  mechanism  and  on  the  top  of  each  of  the  several  float  tube 
bushings.

The  mechanism  and  bushing  numbers  of  an  instrument  must 
correspond. 

Conducting  the  Water  Column  Test 

The  glass  tube  may  be  connected  by  hose  to  the  leading  side  and 
then  placed  alongside  a measuring  rule  arranged  to  extend  vertically 
from  the  water  level  of  the  trailing  side  as  illustrated  in  Fig.  22. 

Close  crossover  valve.  Pour  water  into  the  glass  tube  until  the 
water  level  rises  point  by  point  to  the  three  positions  given  in  the  table 
corresponding  to  the  mechanism  number  for  the  meter  being  tested. 

The  recording  pen,  or  indicating  needle  as  the  case  may  be,  will 
register  the  corresponding  points  given  as  the  water  level  is  elevated 
from  point  to  point.

If  it  is  desired  to  check  the  reading  for  decreasing  flow,  be  sure 
and  preserve  the  zero  by  keeping  the  pipe  T full  of  water.  Fill  the  glass 
tube  full  of  water  and  obtain  the  decreasing  readings  by  carefully 
opening  the  cross  over  valve  X.  If  a glass  tube  is  not  available,  sub- 
stitute iron  piping,  which  will  give  the  desired  water  levels  when 
completely  filled  with  water  for  each  elevation. 

Water  Column  Test  to  Check  Operation  of  the  Air  Flow  Meters,  Types 
F (for  Air)  and  FA-4 

The  air  flow  meter  is  calibrated  to  operate  with  air  above  the 
mercury.  The  test  is  made  by  isolating  the  water  column  in  a U tube. 
One  side  of  the  U tube  is  connected  to  the  leading  side  of  the  meter. 
See  Fig.  23.  Open  the  bleeder  valve  and  then  carefully  crack  the  air 
valve  to  obtain  the  desired  water  columns. 

Due  to  the  absence  of  water  above  the  mercury,  the  water  column 
figures,  corresponding  to  the  3,  6 and  9 lines  of  the  meter  chart,  are 


86503 A-oJf.  Recording  and  Integrating  Flow  Meters 

different  from  those  given  for  steam  and  water  and  a special  tabulation 
is  provided  for  air. 

The  test  is  conducted  in  the  same  manner  as  the  steam  or  water 
meter  test.

INSTRUCTIONS  FOR  OPERATING  AND  TESTING 
TYPES  F,  FS-4,  FA-4  AND  FW-4  METERS  IN 
CONNECTION  WITH  THE  ORIFICE  TUBE 

Orifice  Tubes 

Orifice  tubes  are  used  with  certain  types  of  G-E  steam,  water  and 
air  flow  meters  to  measure  the  flow  in  pipes  2 in.  or  less  in  diameter. 

The  orifice  tube  illustrated  in  Fig.  25  is  designed  to  be  incorporated 
in  the  pipe  line  to  be  metered. 

The  piping,  valves  and  reservoirs,  or  separators  used  with  the  tube 
are  arranged  in  the  same  manner  as  with  the  nozzle  plug. 

Orifice  tubes  for  water  flow , as  shown  by  the  cuts  in  this  book , are  not 
provided  with  outside  drain  piping  as  is  used  for  the  steam  and  air  tubes. 

The  work  of  priming  the  piping  is  conducted  in  the  same  manner 
as  described  for  the  various  nozzle  plug  equipments  for  steam,  air  and 
water. 

The  differential  pressure  obtained  with  the  orifice  tube  is  different 
for  a given  flow  from  that  obtained  with  the  nozzle  plug.  There  is  a 
slight  difference  in  the  spacing  of  the  lines  on  charts  for  recording  meters 
and  also  a difference  in  the  spacing  of  the  main  figures  and  the  three 
test  marks  on  the  indicator  scale.  This  difference  in  the  spacing  of 
the  lines  necessitates  two  sets  of  water  column  figures  for  testing 
respectively  the  steam  or  water  and  the  air  flow  meters  that  are  cali- 
brated for  the  orifice  tube. 

The  charts  of  all  meters  are  properly  marked  to  designate  either 
the  plug  or  the  tube  as  the  basis  of  their  calibration. 


Recording  and  Integrating  Flow  Meters  86503 A— 55 

The  following  tables  give  the  water  column  figures  for  testing. 
The  tests  are  to  be  conducted  in  the  same  manner  as  described  for 
meters  with  nozzle  plug  equipment.

Cleaning 

The  meter  should  be  inspected  and  the  parts  cleaned  and  oiled 
once  a year.  The,  mercury  can  be  cleaned  by  treating  with  dilute 
nitric  acid  and  by  washing  it  in  running  water. 

Whenever  the  water  is  removed  from  the  meter,  the  interior 
surface  and  the  mechanism  should  be  coated  with  oil  to  prevent 
rusting. 

Oil  all  pivot  bearings  and  clock  shafts  once  every  three  months. 


86503 A-56  Recording  and  Integrating  Flow  Meters 

Shipment  of  Meter 

The  meter  is  assembled,  tested  and  inspected  at  the  factory. 
The  movable  parts  of  the  external  mechanism  are  secured  in  place 
before  shipment. 

The  internal  mechanism  is  removed  from  the  meter  and  separately 
boxed. 

The  meter  and  all  parts  are  properly  boxed  for  shipment  and 
should  be  received  in  good  condition. 

All  finished  surfaces  are  oiled  to  prevent  rusting. 

7.  SPECIAL  EQUIPMENT  AND  SUPPLIES 

NORMAL  VELOCITY  AND  HIGH  VELOCITY 
NOZZLE  PLUG  SIZES 

Nozzle  plugs  for  measuring  steam  flow  are  made  up  in  the  follow- 
ing pipe  diameter  sizes:  2,  3,  4,  6,  8,  10,  12,  14,  16,  18,  20,  22,  24,  26, 
28  and  30  inches. 

For  measuring  the  flow  through  a pipe  of  an  intermediate  size, 
use  the  next  smaller  plug,  as  listed  above.  For  example,  for  a pipe  of 
9.05-in.  internal  diameter  use  an  8-in.  nozzle  plug,  as  it  is  only  neces- 
sary that  the  plug  extend  approximately  across  the  diameter  of  the 
pipe. 

The  following  table  gives  the  minimum  internal  pipe  diameter 
with  which  each  size  of  nozzle  plug  can  be  used:

Fig.  31.  TYPE  FS-4  FLOW  METER  CONNECTED  TO 
ORIFICE  TUBE 

PRINCIPLE  OF  OPERATION  OF  THE  G-E  STEAM 
FLOW  METER  EMPLOYING  THE  ORIFICE 
TUBE  TO  OBTAIN  THE  VELOCITY  HEAD 

The  Types  F and  FS-4  meters  will  be  furnished  with  orifice  tubes 
to  measure  the  flow  in  pipes  2 inches  or  less  in  diameter.  The  orifice 
tube  consists  of  a pipe  tapered  internally  at  both  ends  to  form  an 
orifice  near  the  center  of  the  tube.  When  steam  flows  through  the 
tube  there  is  a temporary  reduction  of  pressure  in  the  orifice. 

The  pressure  in  the  pipe  T will,  therefore,  be  the  static  pressure 
minus  a pressure  proportional  to  the  velocity  while  the  pressure  in  the 
pipe  L is  the  static  pressure. 

Due  to  this  differential  pressure  the  mercury  in  the  U tube  of  the 
meter  is  deflected  until  the  unbalanced  column  exactly  balances  the 
differential  pressure.  The  pipe  D acts  as  a drain,  maintaining  equal 
water  columns  on  reservoirs  when  orifice  tube  is  installed  in  a vertical 
pipe. 

Orifice  tubes  are  not  the  same  for  steam,  water  and  air  measure- 
ments.

CIRCULAR  CHARTS  FOR  RECORDING  FLOW 
METERS 

Charts  that  are  accurately  ruled  and  cut  from  the  most  suitable 
paper  are  supplied  by  the  General  Electric  Company. 

There  is  a difference  in  the  spacing  of  the  ten  flow  lines  of  charts 
for  nozzle  plug  service,  relative  to  those  for  the  orifice  tube.  Charts 
must  be  ordered  to  suit. 


86503 A-68  Recording  and  Integrating  Flow  Meters 

Charts  for  either  attachment  can  be  provided  which  have  time 
lines  spaced  as  desired  for  either  1,  8,  12  or  24  hours  per  revolution. 

Each  of  the  eight  different  forms  of  charts  is  given  a designating 
number  which  is  printed  inside  the  zero  circle. 

When  ordering  a supply  of  charts  it  is  sufficient  to  specify  flow 
meter  chart  number,  in  addition  to  stating  the  quantity  wanted. 

Ink 

The  best  quality  of  ink  for  the  recording  pen  is  supplied  by  the 
General  Electric  Company. 

Clocks 

Unless  otherwise  specified,  all  meters  are  furnished  with  clocks  that 
rotate  the  chart  one  revolution  in  24  hours.  For  speeds  of  one  revolu- 
tion per  hour,  or  one  in  eight  or  twelve  hours,  special  clocks  will  be 
furnished. 

8.  STEAM,  AIR  AND  WATER  FLOW  TABLES 

The  range  of  flow  to  be  measured  determines  whether  a normal  velocity 
nozzle  plug , high  velocity  nozzle  plug  or  pipe  reducer  is  required  for  any 
given  condition  of  pressure , quality  and  pipe  diameter. 

In  selecting  the  proper  nozzle  plug  or  pipe  reducer  to  be  used  always 
choose  that  one  corresponding  to  the  diameter  of  the  pipe  in  which  the  steam 
is  to  be  measured  and  whose  range  of  flow  is  nearest  to , but  not  less  than 
that  which  the  meter  is  to  measure.  This  must  be  strictly  adhered  to  if 
accurate  results  from  the  meter  are  desired. 

If  the  existing  steam  pressure  is  other  than  that  given  in  the  table  the 
range  of  flow  which  can  be  measured  with  the  meter  may  be  closely  approxi- 
mated by  interpolation. 

Examples 

Nominal  pipe  diameter,  6 inches. 

Pressure,  150  lb.  gauge. 

Quality  of  steam,  1 per  cent  moisture. 

Case  I. — Flow  to  be  measured  by  the  meter  0 to  33,000  lb.  per  hr., 
use  Cat.  No.  136598,  normal  velocity  nozzle  plug. 

Case  II. — Flow  to  be  measured  by  the  meter  0 to  10,000  lb.  per 
hr.,  use  Cat.  No.  139662,  6-in.  by  3-in.  pipe  reducer  and  nozzle  plug. 

Case  III. — Flow  to  be  measured  by  the  meter  0 to  12,000  lb.  per 
hr.,  use  Cat.  No.  143670,  6-in.  by  3 3^-in.  pipe  reducer  and  nozzle  plug. 

Case  IV. — Flow  to  be  measured  by  the  meter  0 to  15,000  lb.  per 
hr.,  use  Cat.  No.  143671,  6-in.  by  4-in.  pipe  reducer  and  nozzle  plug. 

Case  V. — Elow  to  be  measured  by  the  meter  0 to  45,000  lb.  per 
hr.,  use  Cat.  No.  143685,  high  velocity  nozzle  plug. 

30  pounds  of  steam  equal  1 boiler  horse  power.

Normal  velocity  nozzle  plugs  can  not  be  furnished  for  pipes  less  than  2 inches 
in  diameter  but  can  be  furnished  for  pipes  larger  than  14  inches  if  desired. 

For  odd  diameter  pipes  use  the  next  smaller  nozzle  plug  listed;  for  example,  use 
a 6-inch  nozzle  plug  in  a 7-inch  pipe. 

The  flows  in  above  table  are  for  meter  with  the  large  No.  7 mechanism.  To  find 
maximum  flows  for  other  sizes  of  mechanism  multiply  above  figures  by  constants

Cat.  Nos.  include  pipe  reducer  complete  with  nozzle  plug. 

Pipe  reducers  can  not  be  furnished  for  pipes  less  than  4 inches  in  diameter,  but  can 
be  furnished  for  pipes  larger  than  14  inches,  if  desired.  If  it  is  necessary  to  reduce  the 
area  of  a 3-inch  pipe  a smaller  section  should  be  installed. 

The  flows  in  above  table  are  for  meter  with  the  large  No.  7 mechanism.  To  find 
maximum  flows  for  other  sizes  of  mechanism  multiply  above  figures  by  constants 
from  page  29.

High  velocity  nozzle  plugs  can  not  be  furnished  for  pipes  less  than  2 inches  in 
diameter,  but  can  be  furnished  for  pipes  larger  than  14  inches,  if  desired. 

For  odd  diameter  pipes  use  the  next  smaller  nozzle  plug  listed;  for  example,  use  a 
6-inch  nozzle  plug  in  a 7-inch  pipe. 

The  flows  in  above  table  are  for  meter  with  the  large  No.  7 mechanism.  To  find 
maximum  flows  for  other  sizes  of  mechanism  multiply  above  figures  by  constants 
from  page  29. 


Recording  and  Integrating  Flow  Meters  86503 A-73 

ORIFICE  TUBES  FOR  USE  WITH  THE  G-E 
RECORDING  STEAM  FLOW  METER 
TYPES  F AND  FS-4 

In  selecting  the  proper  orifice  tube  to  be  used  always  choose  that  one 
corresponding  to  the  diameter  of  the  pipe  in  which  the  steam  is  to  be 
measured  and  whose  range  of  flow  is  nearest  to,  but  not  less  than  that  which 
the  meter  is  to  measure.  This  must  be  strictly  adhered  to  if  accurate  results 
from  the  meter  are  desired. 

If  the  existing  steam  pressure  is  other  than  that  given  in  the  table  the 
range  of  flow  which  can  be  measured  with  the  meter  may  be  closely  approxi- 
mated by  interpolation. 

Examples 

Nominal  pipe  diameter,  13^  inches. 

Pressure,  150  lb.  gauge. 

Quality  of  steam,  1 per  cent  moisture. 

Case  I. — Flow  to  be  measured  by  the  meter  0 to  200  lb.  per  hr., 
use  Cat.  No.  128434,  orifice  tube. 

Case  II. — Flow  to  be  measured  by  the  meter  0 to  300  lb.  per  hr., 
use  Cat.  No.  128435,  orifice  tube. 

Case  III. — Flow  to  be  measured  by  the  meter  0 to  600  lb.  per  hr., 
use  Cat.  No.  128436,  orifice  tube. 

30  pounds  of  steam  equal  1 boiler  horse  power.

NOZZLE  PLUGS  AND  PIPE  REDUCERS  FOR 
G-E  RECORDING  AIR  FLOW  METERS 
TYPES  F AND  FA-4 

The  range  of  flow  to  he  measured  determines  whether  a normal  velocity 
nozzle  plug , high  velocity  nozzle  plug  or  pipe  reducer  is  required  for  any 
given  condition  of  pressure , temperature  and  pipe  diameter. 

In  selecting  the  proper  nozzle  plug  or  pipe  reducer  to  he  used  always 
choose  that  one  corresponding  to  the  diameter  of  the  pipe  in  which  the  air 
is  to  he  measured  and  whose  range  of  flow  is  nearest  to,  hut  not  less  than 
that  which  the  meter  is  to  measure.  This  must  he  strictly  adhered  to  if 
accurate  results  from  the  meter  are  desired. 

If  the  existing  air  pressure  is  other  than  that  given  in  the  table  the 
range  of  flow  which  can  he  measured  with  the  meter  may  he  closely  approxi- 
mated hy  interpolation. 

Examples 

Nominal  pipe  diameter,  6 inches. 

Pressure,  100  lb.  absolute. 

Temperature  of  air,  80  deg.  F. 

Case  I. — Flow  to  be  measured  by  the  meter,  0 to  8000  cu.  ft., 
use  Cat.  No.  136598,  normal  velocity  nozzle  plug. 

Case  II. — Flow  to  be  measured  by  the  meter,  0 to  2600  cu.  ft., 
use  Cat.  No.  139662,  6-in.  by  3-in.  pipe  reducer  and  nozzle  plug. 

Case  III.— -Flow  to  be  measured  by  the  meter  0 to  3000  cu.  ft., 
use  Cat.  No.  143670,  6-in.  by  33^2-in.  pipe  reducer  and  nozzle  plug. 

Case  IV. — Flow  to  be  measured  by  the  meter,  0 to  4200  cu.  ft., 
use  Cat.  No.  143671,  6-in.  by  4-in.  pipe  reducer  and  nozzle  plug. 

Case  V. — Flow  to  be  measured  by  the  meter  0 to  14,000  cu.  ft., 
use  Cat.  No.  143685,  high  velocity  nozzle  plug. 

Note. — The  flows  given  in  the  examples  are  cubic  feet  of  free  air 
(14.7  lb.  absolute  pressure)  per  minute  at  70  deg.  F.  temperature.

High  velocity  nozzle  plugs  can  not  be  furnished  for  pipes  less  than  2 inches  in 
diameter,  but  can  be  furnished  for  pipes  larger  than  14  inches,  if  desired. 

The  flows  given  in  this  table  are  cubic  feet  of  free  air  (14.7  lb.  absolute  pressure) 
per  minute  at  70  deg.  F.  temperature. 

For  odd  diameter  pipes  use  the  next  Smaller  size  nozzle  plug  listed;  for  example, 
use  a 6-inch  nozzle  plug  in  a 7-inch  pipe. 

The  flows  in  above  table  are  for  meter  with  the  large  No.  7 mechanism.  To  find 
maximum  flows  for  other  sizes  of  mechanism  multiply  above  figures  by  constants 
from  page  29.

TYPES  F AND  FA-4 

In  selecting  the  proper  orifice  tube  to  be  used  always  choose  that  one 
corresponding  to  the  diameter  of  the  pipe  in  which  the  air  is  to  be  measured 
and  whose  range  of  flow  is  nearest  to,  but  not  less  than  that  which  the  meter 
is  to  measure.  This  must  be  strictly  adhered  to  if  accurate  results  from  the 
meter  are  desired. 

If  the  existing  air  pressure  is  other  than  that  given  in  the  table  the 
range  of  flow  which  can  be  measured  with  the  meter  may  be  closely  approxi- 
mated by  interpolation. 

Examples 

Nominal  pipe  diameter,  1^  inches. 

Pressure,  100  lb.  absolute. 

Temperature  of  air,  80  deg.  F. 

Case  I. — Flow  to  be  measured  by  the  meter,  0 to  50  cu.  ft.,  use 
Cat.  No.  128446,  orifice  tube. 

Case  II. — Flow  to  be  measured  by  the  meter,  0 to  120  cu.  ft.,  use 
Cat.  No.  128447,  orifice  tube. 

Case  III. — Flow  to  be  measured  by  the  meter,  0 to  200  cu.  ft.,  use 
Cat.  No.  128448,  orifice  tube. 

The  flows  given  in  the  ex*amples  are  cubic  feet  of  free  air  (14.7  lb. 
absolute  pressure)  per  minute  at  70  deg.  F.  temperature.

The  range  of  flow  to  be  measured  determines  whether  a normal  velocity 
nozzle  plug , high  velocity  nozzle  plug  or  pipe  reducer  is  required  for  any 
given  pipe  diameter. 

In  selecting  the  nozzle  plug  or  pipe  reducer  to  be  used  always  choose 
that  one  corresponding  to  the  diameter  of  the  pipe  in  which  the  water  is  to  be 
measured  and  whose  range  of  flow  is  nearest  to , but  not  less  than  that 
which  the  meter  is  to  measure.  This  must  be  strictly  adhered  to  if  accurate 
results  from  the  meter  are  desired. 

Examples 

Nominal  pipe  diameter,  6 inches. 

Temperature  of  water,  80  deg.  F.
